Implementation of a MultipleQueue class to consume from multiple queues at once

[pfreixes]

Just as a question before try to implement it and get some feedback from @gmr and users of the Rabbitpy community.

I'm implementing a set of experiments using different AMQP Python drivers such as Pika, Librrabbitmq and so on [1] using a kind of fair scheduling - consuming from many queues - and I would like to get some numbers with the Rabbitpy driver. But I saw that there is no support to consume several queues from one consumer, and now I able to to that only with a N:N correlation between threads/consumers and queues.

In fact the idea behind this trial is just move to a correlation like N:M where the number of threads/consumers as N are always below the number for queues.

To make that Rabbitpy would need a new class - let's say MultipleQueue - that would consume messages from different queues without a strict order, just processing them as they arrive, leaving all of the fairness to the Rabbitmq broker.

Is that interesting ?
